Can a field that has been planted with astragalus be planted with bud rice?

Those who have planted this can also grow buds, and they need to renovate the land and then apply some fertilizer again, and there is no problem at all.

Yes, before planting astragalus, the soil should be selected, choose some soil with good ventilation, strong drainage and irrigation, fertile soil and high terrain, and the water content in the soil must also reach enough sandy loam land, and at the same time, because astragalus is more like cold and sunny places, it is necessary to sort out the land to varying degrees. When the planting land is selected, the soil should be organized, and the land should be prepared in late autumn or early winter, and all the debris in the soil should be removed during land preparation, and the soil should be deeply turned. All the land should be turned down about 50 centimeters deep, exposed to the sun, winterized and frozen, in order to reduce the damage of pests and diseases in the soil, as well as some weeds.

It is possible to grow bud rice in the field where medicinal herbs have been planted, because this does not allow the plant to absorb the nutrients it needs in different soils without growing tea. The growth of bracts is relatively tenacious, and medicinal herbs. He's more dense, but be careful.

The land where medicinal herbs are planted is prone to more weeds, and when the buds are planted again, the absorption of the roots of the buds will be affected. Prone to water shortage, drought.

The best choice for growing loose crops in astragalus stubble is rapeseed. Oilseed rape is a greenhouse slag digging crop that can be grown in spring and autumn and has a high economic value and can provide nutritious food. Rapeseed cultivation requires fertile and well-drained soil, with an organic matter content of 3%!

On (missing), the pH value is between, the soil moisture requirement is high, irrigated 2-3 times a day, and the amount of each irrigation is quietly 2-3 ml square meters.

1. Land selection and land preparation: Astragalus is a deep-rooted crop, and neutral or slightly acidic sandy loam with deep soil layer, loose soil, fertile soil, good drainage, and high dryness to the sun can be planted on flat or sunny slopes. Before sowing, apply bottom fertilizer, deep ploughing, watering and spraying the soil surface with a new high-lipid film, which can protect moisture and waterproof evaporation, sunscreen and drought resistance, heat preservation and antifreeze, soil layer compaction, suffocation and isolation of pest and disease sources, and improve the emergence rate.

2. Seed propagation: using seed propagation method, seed treatment, because the seed coat of Astragalus membranaceus is hard and impermeable, and there is a dormant state, it must be promoted by mechanical, physical or chemical methods to promote its germination. Mechanical damage is the most convenient and fast, the seeds are quickly rolled several times with a stone mill, so that the outer seed coat changes from brown-black shiny to gray-brown when the epidermis is rough, so as to facilitate the seeds to absorb water and expand.

You can also mix the seeds into 2 times the fine sand and rub them, and when you scratch the seed coat, you can take the sand to plant.

3. Field management: thinning, seedling, seedling replenishment When the seedling height is 5-7cm, the first seedling is carried out, and the seedling is replenished in a timely manner according to the needs of the plant. Cultivating weeding, Astragalus seedlings grow slowly, and it is easy to cause grass shortage if you do not pay attention to weeding, so when the seedling height is about 5cm, it is necessary to carry out weeding in time in combination with seedlings.

Top dressing, astragalus fertilizer, in the first year of growth, combined with cultivating and weeding once a year to chase Israel fertile leaf functional fertilizer, after application soil antifreeze, the later stage should pay attention to the use of fertile leaf phosphorus and potassium fertilizer.

Topping, in order to control the height of plant growth and reduce nutrient consumption, topping is carried out before the end of July, and spraying medicinal herbs can promote the delivery of foliar photosynthesis products (nutrients) to the root system, improve the nutrient conversion rate and soil loosening ability, make the rhizome expand rapidly, and the content of effective substances is greatly improved.

4. Pest control: powdery mildew, astragalus purple feather disease, commonly known as "red root disease", aphids, pod borer, etc., spray targeted drugs and new high-lipid films, greatly improve the utilization rate of active ingredients of pesticides, not afraid of sun exposure and evaporation, can adjust the absorption of water, drought and rain.

Let's see what is suitable for growing there, and it is best to grow something that is wild in the local area, so that the yield and quality will be good.
